Give us an idea what you DO know so we know where to start..

Can you presently record a track in PTPA?
What did you use to record it?

If you can record a track of (say) guitar, hook up the bass the same way, highlite a different track and record it the same way.

When it comes time to record vocals, hook up a mic (with a preamp probably, like a mixer) and record that onto a different track.

Let us know where you hit the stumbling block. Then we can give better answers
